Problem summary

  • ****************************************************************
    * USERS AFFECTED: All DB2 10 and DB2 11 for z/OS users who     *
    *                 use IBM DB2 Analytics Accelerator.           *
    ****************************************************************
    * PROBLEM DESCRIPTION: -STOP ACCEL command hangs when there    *
    *                      is no thread off-loaded to the remote   *
    *                      Accelerator.                            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    DB2 registered a thread that was intended to off-load to the
    remote Accelerator.  However, in certain cases, this thread may
    not off-load after all and deregistration may be delayed if the
    thread continues servicing other work.  This will result in a
    hang of -STOP ACCEL command processing.
    

Problem conclusion

  • DB2 has been changed to register accelerator interest only
    when actually necessary.
